Walter Miller translation
Decorum Cicero's attempt to translate πρέπον, means an appreciation of the fitness of things, propriety in inward feeling or outward appearance, in speech, behaviour, dress, etc. Decorum is as difficult to translate into English as πρέπον is to reproduce in Latin; as an adjective, it is here rendered by 'proper,' as a noun, by 'propriety.'
